I have such mixed emotions about this... On one hand, I like the idea of a Shields, Lohse, Garza, Peralta, Fiers rotation a ton. However, I still think the Brewers could be a little light on O at 1B, SS, 2B and to be honest, 3B, to be true contenders. Trading Nelson to get you back something that could immensely help your chances of contending this season but could hurt once Lohse goes and the 5th spot in the rotation has to be filled by an unknown like Jungmann. I guess for me the real problem with signing Shields is that by itself I don't think it moves the Brewers from fringe contender to a true pennant contender in 2015. Now Shields and a trade of Nelson for a complete 1B like Fielder (I know) or Chris Davis, or a MLB-ready 3B prospect like Cecchini should Ramirez fall off or get hurt, and you might have something for 2015. A rotation like the one mentioned above combined with a middle of the order that has Gomez-Braun-Fielder/Davis-Lucroy-Ramirez-Davis has a real shot at contention.
